Silica Gel, Anhydrous (112926-00-8)

Partly dehydrated polymerised, amorphous silicic acid, absorbing at 20 °C about 30% of its mass of water. Practically insoluble in water, partly soluble in solutions of sodium hydroxide. It contains a suitable indicator for detection of the humidity status, for which the colour change from the hydrated to anhydrous form is given on the label.
